	  'no ip ospf authentication A.B.C.D', 'no ip ospf
	  authentication-key A.B.C.D'. Simply fix argv's indexes and
          argc check in DEFUN functions.

6f0e3f6e17 [autoconf] bugs 162,303,178: Fix 'present but can not be compiled' warnings
2007-05-09 Paul Jakma <paul.jakma@sun.com>

	* configure.ac: sys/conf.h depends on sys/param.h, at least on
	  FBSD 6.2.
	  (bug #363) Should check for in_pktinfo for IRDP

2006-05-27 Paul Jakma <paul.jakma@sun.com>

	* configure.ac: General cleanup of header and type checks, introducing
	  an internal define, QUAGGA_INCLUDES, to build up a list of
	  stuff to include so as to avoid 'present but cant be compiled'
	  warnings.
	  Misc additional checks of things missing according to autoscan.
	  Add LIBM, for bgpd's use of libm, so as to avoid burdening
	  LIBS, and all the binaries, with libm linkage.
	  Remove the bad practice of using m4 changequote(), just
	  quote the []'s in the case statements properly.
	  This should fix bugs 162, 303 and 178.
	* */*.{c,h}: Update all HAVE_* to the standard autoconf namespaced
	  HAVE_* defines. I.e. HAVE_SA_LEN -> HAVE_STRUCT_SOCKADDR_SA_LEN,
	* bgpd/Makefile.am: Add LIBM to bgpd's LDADD, for pow().

08d3d5b398 [ospfd] Bug #330 regression: Fix ospf_spf_add_parent assert
2007-05-07 Paul Jakma <paul.jakma@sun.com>

	* ospf_spf.c: (ospf_vertex_new) Dont init vertices to infinity,
	  just let 0 be a special case.
	  (ospf_spf_add_parent) 0 distance candidate vertex is special,
	  cost still to be initialised - asserting that new distance
	  is <= existing only makes sense where w already has a cost.
	  (ospf_spf_next) Infinite cost links should not be followed,
	  bar those of the root.

f0ec832a78 [ospfd] network command now behaves more logically when a peer prefix is defined
2007-04-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* ospfd/ospfd.c: (ospf_network_match_iface) Comment out
	  COMPATIBILITY_MODE.  Going forward, the ospf "network" command
	  will use a simple test: does the network command prefix
	  contain the connected (destination) prefix of the interface?
	* doc/ospfd.texi: Add a paragraph to the description of the OSPFv2
	  network command to explain how we handle interfaces with
	  peer addresses.

2007-04-21 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* ospf_interface.c: (ospf_if_set_multicast) Fix bug: was testing
	  interface passive status improperly in light of the recent
	  'passive-interface default' patch.  Now need to test
	  OSPF_IF_PASSIVE_STATUS(oi) instead of
	  OSPF_IF_PARAM(oi, passive_interface).

2007-03-14 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

56b3ea09bb [ospfd] Fix two debug messages that used inet_ntoa more than once
2007-03-14 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* ospf_zebra.c: (ospf_zebra_add, ospf_zebra_delete) Fix bug
	  where inet_ntoa was used twice in the same debug message,
	  which doesn't work because there's a single shared buffer
	  for the returned string.  The fix is to use inet_ntop.

4056a544eb [ospfd] Fix bug: should exit immediately on SIGTERM if OSPF not actually running
2007-02-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* ospfd.c: (ospf_terminate) Exit immediately if ospf is not
	  actually running (e.g. the config file was empty).  Fixes
	  bug where SIGTERM would not kill ospfd.

bd34fb346d [ospfd] Fix regression in SPF introduced by bug#330 fixes
2007-02-26 Paul Jakma <paul.jakma@sun.com>

	* ospf_spf.c: Fix regression introduced with bug #330 fix: The
	  cost update added to ospf_spf_add_parent only handled PtP
	  case, differing from same functionality in higher-level
	  ospf_spf_next. Regression diagnosed by Anders Pedersen,
	  mailnews+router-quagga-dev@news.cohaesio.com.
	  (ospf_vertex_new) Initialise vertices to max-cost.
	  (ospf_spf_init) Root vertex always creates with 0 cost.
	  (ospf_spf_add_parent) Remove the buggy V->W cost calculating
	  code, instead take the new distance as a parameter.
	  (ospf_nexthop_calculation) Take distance as parameter, so it
	  can be passed down to add_parent.
	  (ospf_spf_next) Dont initialise candiate vertex distance,
	  vertex_new does so already. Pass distance down to
	  nexthop_calculation (see above).

bc20c1a463 [ospfd] Bug #330: SPF must consider that nexthop-calc may fail
2007-01-24 Paul Jakma <paul.jakma@sun.com>

	* ospf_spf.c: Bug #330: Nexthop calculation sometimes may fail,
	  and it needs to indicate this result to SPF.
	  (ospf_spf_add_parent) Flush of parent list needs to be done here,
	  for simplicity.
	  (ospf_nexthop_calculation) Caller needs to know whether
	  nexthop calculation succeeded. Every return statement must
	  correctly indicate such.
	  (ospf_spf_next) Queueing/prioritisation of vertices in SPF
	  must take into account whether nexthop_calculation succeeded,
	  or SPF may fail to find best paths.

e4529636b7 [PtP over ethernet] New peer flag allows much more addressing flexibility
2006-12-12 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* if.h: (struct connected) Add new ZEBRA_IFA_PEER flag indicating
	  whether a peer address has been configured.  Comment now shows
	  the new interpretation of the destination addr: if ZEBRA_IFA_PEER
	  is set, then it must contain the destination address, otherwise
	  it may contain the broadcast address or be NULL.
	  (CONNECTED_DEST_HOST,CONNECTED_POINTOPOINT_HOST) Remove obsolete
	  macros that were specific to IPv4 and not fully general.
	  (CONNECTED_PEER) New macro to check ZEBRA_IFA_PEER flag.
	  (CONNECTED_PREFIX) New macro giving the prefix to insert into
	  the RIB: if CONNECTED_PEER, then use the destination (peer) address,
	  else use the address field.
	  (CONNECTED_ID) New macro to come up with an identifying address
	  for the struct connected.
	* if.c: (if_lookup_address, connected_lookup_address) Streamline
	  logic with new CONNECTED_PREFIX macro.
	* prefix.h: (PREFIX_COPY_IPV4, PREFIX_COPY_IPV6) New macros
	  for better performance than the general prefix_copy function.
	* zclient.c: (zebra_interface_address_read) For non-null destination
	  addresses, set prefixlen to equal the address prefixlen.  This
	  is needed to get the new CONNECTED_PREFIX macro to work properly.
	* connected.c: (connected_up_ipv4, connected_down_ipv4,
	  connected_up_ipv6, connected_down_ipv6) Simplify logic using the
	  new CONNECTED_PREFIX macro.
	  (connected_add_ipv4) Set prefixlen in destination addresses (required
	  by the CONNECTED_PREFIX macro).  Use CONNECTED_PEER macro instead
	  of testing for IFF_POINTOPOINT.  Delete invalid warning message.
	  Warn about cases where the ZEBRA_IFA_PEER is set but no
	  destination address has been supplied (and turn off the flag).
	  (connected_add_ipv6) Add new flags argument so callers may set
	  the ZEBRA_IFA_PEER flag.  If peer/broadcast address satisfies
	  IN6_IS_ADDR_UNSPECIFIED, then reject it with a warning.
	  Set prefixlen in destination address so CONNECTED_PREFIX will work.
	* connected.h: (connected_add_ipv6) Add new flags argument so
	  callers may set the ZEBRA_IFA_PEER flag.
	* interface.c: (connected_dump_vty) Use CONNECTED_PEER macro
	  to decide whether the destination address is a peer or broadcast
	  address (instead of checking IFF_BROADCAST and IFF_POINTOPOINT).
	* if_ioctl.c: (if_getaddrs) Instead of setting a peer address
	  only when the IFF_POINTOPOINT is set, we now accept a peer
	  address whenever it is available and not the same as the local
	  address.  Otherwise (no peer address assigned), we check
	  for a broadcast address (regardless of the IFF_BROADCAST flag).
	  And must now pass a flags value of ZEBRA_IFA_PEER to
	  connected_add_ipv4 when a peer address is assigned.
	  The same new logic is used with the IPv6 code as well (and we
	  pass the new flags argument to connected_add_ipv6).
	  (if_get_addr) Do not bother to check IFF_POINTOPOINT: just
	  issue the SIOCGIFDSTADDR ioctl and see if we get back
	  a peer address not matching the local address (and set
	  the ZEBRA_IFA_PEER in that case).  If there's no peer address,
	  try to grab SIOCGIFBRDADDR regardless of whether IFF_BROADCAST is set.
	* if_ioctl_solaris.c: (if_get_addr) Just try the SIOCGLIFDSTADDR ioctl
	  without bothering to check the IFF_POINTOPOINT flag.  And if
	  no peer address was found, just try the SIOCGLIFBRDADDR ioctl
	  without checking the IFF_BROADCAST flag.  Call connected_add_ipv4
	  and connected_add_ipv6 with appropriate flags.
	* if_proc.c: (ifaddr_proc_ipv6) Must pass new flags argument to
	  connected_add_ipv6.
	* kernel_socket.c: (ifam_read) Must pass new flags argument to
	  connected_add_ipv6.
	* rt_netlink.c: (netlink_interface_addr) Copy logic from iproute2
	  to determine local and possible peer address (so there's no longer
	  a test for IFF_POINTOPOINT).  Set ZEBRA_IFA_PEER flag appropriately.
	  Pass new flags argument to connected_add_ipv6.
	  (netlink_address) Test !CONNECTED_PEER instead of if_is_broadcast
	  to determine whether the connected destination address is a
	  broadcast address.
	* bgp_nexthop.c: (bgp_connected_add, bgp_connected_delete)
	  Simplify logic by using new CONNECTED_PREFIX macro.
	* ospf_interface.c: (ospf_if_is_configured, ospf_if_lookup_by_prefix,
	  ospf_if_lookup_recv_if) Simplify logic using new CONNECTED_PREFIX
	  macro.
	* ospf_lsa.c: (lsa_link_ptop_set) Using the new CONNECTED_PREFIX
	  macro, both options collapse into the same code.
	* ospf_snmp.c: (ospf_snmp_if_update) Simplify logic using new
	  CONNECTED_ID macro.
	  (ospf_snmp_is_if_have_addr) Simplify logic using new CONNECTED_PREFIX
	  macro.
	* ospf_vty.c: (show_ip_ospf_interface_sub) Use new CONNECTED_PEER macro
	  instead of testing the IFF_POINTOPOINT flag.
	* ospfd.c: (ospf_network_match_iface) Use new CONNECTED_PEER macro
	  instead of testing with if_is_pointopoint.  And add commented-out
	  code to implement alternative (in my opinion) more elegant behavior
	  that has no special-case treatment for PtP addresses.
	  (ospf_network_run) Use new CONNECTED_ID macro to simplify logic.
	* rip_interface.c: (rip_interface_multicast_set) Use new CONNECTED_ID
	  macro to simplify logic.
	  (rip_request_interface_send) Fix minor bug: ipv4_broadcast_addr does
	  not give a useful result if prefixlen is 32 (we require a peer
	  address in such cases).
	* ripd.c: (rip_update_interface) Fix same bug as above.

ed589c1577 [ospfd] Consider all connected addresses when creating ospf interfaces
2006-12-04 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* ospfd.c: (ospf_network_run) Remove an offending 'break' statement.
	  Previously, after creating a single ospf_interface on a given
	  network interface, the code would skip to the next interface
	  without considering other connected addresses on the interface.
	  After removing the 'break', we now consider all connected addresses.

7f643ebf2b [ospfd] Add debug messages for a few zebra messages that had been overlooked

	* ospf_zebra.c: (ospf_router_id_update_zebra,
	  ospf_interface_address_add, ospf_interface_address_delete)
	  If (IS_DEBUG_OSPF (zebra, ZEBRA_INTERFACE)) is enabled, then
	  add a debug message about what Zebra is telling us.
	  (ospf_zebra_add_discard) Add a debug message matching the one
	  already in ospf_zebra_delete_discard.

4354088661 [ospfd] Fix bug in passive-interface default commands.
2006-11-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* ospf_vty.c: (ospf_passive_interface_default) Take additional
	  'newval' arg so we can update ospf->passive_interface_default inside
	  this function.  More importantly, we now call ospf_if_set_multicast
	  on all ospf_interfaces.
	  (ospf_passive_interface, no_ospf_passive_interface) Fix bug:
	  for 'default' case, argv[0] is undefined, so we must test for
	  (argc == 0) before using argv[0].  And since
	  ospf_passive_interface_default now calls ospf_if_set_multicast as
	  needed, we can just return after calling
	  ospf_passive_interface_default.

	* ospf_zebra.c: (ospf_redistribute_default_set) Fix bug where

	  had already been processed.

7ffa8fa232 [ospfd] Add passive-interface default support
2006-10-22 Yar Tikhiy <yar@comp.chem.msu.su>

	* (general) Add support for passive-interface default (with
	  minor edits by Paul Jakma).
	* ospf_interface.h: Add OSPF_IF_PASSIVE_STATUS macro, looking
	  at configured value, or the global 'default' value, as
	  required.
	* ospf_interface.c: (ospf_if_new_hook) Leave passive
	  unconfigured per default, allowing global 'default' to
	  take effect for unconfigured interfaces.
	* ospf_packet.c: (various) use OSPF_IF_PASSIVE_STATUS
	* ospf_vty.c: (ospf_passive_interface_default) new function,
	  unset passive from all interfaces if default is enabled, as
	  the per-iface settings become redundant.
	  (ospf_passive_interface_update) new func, update passive
	  setting taking global default into account.
	  ({no,}ospf_passive_interface_addr_cmd) Add support for
	  'default' variant of command.
	  (show_ip_ospf_interface_sub) Update to take global
	  default into account when printing passive status.
	  (ospf_config_write) ditto.
	* ospfd.c: (ospf_new) set global passive-interface default.

876b8be0ab [daemon startup] Add --dry-run/-C argument to daemons, to check config file syntax
2006-10-04 Oliver Hookins <ohookins@gmail.com>

	* bgpd/bgp_main.c: Add configuration check option, with

	* zebra/main.c: ditto

2006-10-04 Stergiakis Alexandros <astergiakis@antcor.com>

	* ripd/rip_main.c: This trivial patch introduces a new
	  command-line option '-c', which instructs zebra/ripd
	  to check its configuration file for validity,	print
	  any error message, and then exit. This is useful when
	  the configuration file is edited by hand or otherwise,
	  and you simply want to validate it without any other
	  effect.

1670008b54 [ospfd] Bug #288: do not change router ID unless forced by manual configuration
2006-07-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* ospfd.c: (ospf_router_id_update) Fix and document the algorithm for
	  selecting the router ID: if there is not a statically configured ID,
	  then stick to the most recent value to avoid disruptive changes.
	  This should fix bug #288.

1fe6ed38cd [ospfd] Allow ospf_lsa_unlock to NULL out callers' LSA pointers upon free
2006-07-26 Paul Jakma <paul.jakma@sun.com>

	* ospf_lsa.{c,h}: (ospf_lsa_unlock) Change to take a double pointer
	  to the LSA to be 'unlocked', so that, if the LSA is freed, the
	  callers pointer to the LSA can be NULLed out, allowing any further
	  use of that pointer to provoke a crash sooner rather than later.
	* ospf_*.c: (general) Adjust callers of ospf_lsa_unlock to match
	  previous. Try annotate 'locking' somewhat to show which 'locks'
	  are protecting what LSA reference, if not obvious.
	* ospf_opaque.c: (ospf_opaque_lsa_install) Trivial: remove useless
	  goto, replace with return.
	* ospf_packet.c: (ospf_make_ls_ack) Trivial: merge two list loops,
	  the dual-loop predated the delete-safe list-loop macro.

3d63f38064 [ospfd] trivial: NSM AdjChange should print event, declutter core functions
2006-07-10 Paul Jakma <paul.jakma@sun.com>

	* ospf_nsm.c: (nsm_notice_state_changes) Move state change
	  logging code to new func to declutter nsm_change_state and
	  ospf_nsm_event.
	  Log event with AdjChange, it's useful to know.
	  (nsm_change_state) move adjchange and snmp logging to previous.
	  (ospf_nsm_event) call nsm_notice_state_changes from here.
	  Move the debug message to entry of function, so it gets out
	  even if something goes wrong.

2006-07-10 Paul Jakma <paul.jakma@sun.com>

	* ospf_nsm.c: (nsm_change_state) call nsm_clear_adj for all
	  adjacency losses, hence removing need for nsm_reset_nbr.
	  (nsm_reset_nbr) kill it, clear_adj in previous does fine.
	  (nsm_kill_nbr,nsm_start) remove nsm_reset_nbr call.
	  (ospf_nsm_event) Allow NSM function to be NULL, this along with
	  removal of nsm_reset_nbr, allows a bunch of now useless functiosn
	  to be removed.
	  Remove some useless variables.
	  (nsm_ignore) now useless, remove.

1f2c2743ac [ospfd] cleanup NSM neighbour delete through a new Deleted NSM state
2006-07-07 Paul Jakma <paul.jakma@sun.com>

	* ospf_nsm.h: Add a NSM_Deleted neighbour state, to act as dummy
	  state indicating the neighbour is to be deleted.
	* ospf_nsm.c: (general) Use the NSM_Deleted state to delete
	  neighbours, thus allowing code to be slightly more obvious
	  in its flow.
	  (nsm_timer_set) Add NSM_Deleted. Add another timer the code
	  missed.
	  (nsm_kill_nbr) No need for special case call to nsm_change_state
	  anymore.
	  Make the assert and error-handling for same case more readable
	  (Andrew Schorr)
	  Remove the call to ospf_nbr_delete, nsm_change_state can do
	  this generally now via NSM_Deleted.
	  (struct ... NSM) Add the dummy NSM_Deleted state, the 3 events
	  that can lead to nsm_kill_nbr all now transition the NBR to
	  NSM_Deleted and the general change_state function can be left
	  to do the work.
	  (ospf_nsm_event) Special casing of events and early-return can
	  be removed now.
	  On transition into Deleted, delete the nbr.
	* ospf_dump.c: (ospf_nsm_state_msg) Add Deleted.

aa2737a08a [ospfd] early-return in nsm_event missed LLDown event, fixes use after free
2006-07-06 Paul Jakma <paul.jakma@sun.com>

	* ospf_nsm.c: (ospf_nsm_event) LLDown event also results in nbr
	  being deleted, requires early-return too. Likely explains
	  some crash reports after interface events.

	  (nsm_should_adj) Can just be one big OR.

d1b1cd8fb9 [ospfd] Clear adjacency state for NSM changes down to TwoWay/ExStart
2006-07-02 Paul Jakma <paul.jakma@sun.com>

	* ospf_nsm.c: (nsm_clear_adj) clear adjacency related state for a
	  neighbour, needed for some state changes from > ExStart down
	  to ExStart or less, which need not go through nsm_reset_nbr.
	  (nsm_reset_nbr) move code to former. Should be static.
	  (ospf_nsm_event) Remove long dead code.
	  Use nsm_clear_adj for state changes that take down
	  adjacencies to TwoWay/ExStart.
	  (nsm_kill_nbr) Oops, action function shouldn't try return
	  1 for error.

ba0beb4a84 [ospfd] Ensure NSM state functions can redirect next_state accidently

	* ospf_nsm.c: (ospf_nsm_event) Don't allow action functions to
	  change next_state if the NSM tables do not indicate
	  next_state is conditional, log warning if one tries -
	  existing code appears fine though.

7694787c19 [ospfd] Avoid getting NSM stuck in ExStart by using local view of DR/BDR
2006-06-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* ospf_nsm.c: (nsm_twoway_received) When deciding whether to
	  change from state Init to ExStart, the test for whether the
	  neighboring router is DR or BDR should be against the
	  local router's notion of DR/BDR, not the neighbor's view.
